Abstract
A bearing lubricating housing (100) comprising a lubricating housing body (110). The bearing housing (100) is designed to retain a rolling element bearing assembly (200) while providing axial motion when the housing (100) is assembled within an interior of a guiding tube (310). The bearing housing (100) includes a series of channels (118) and/or passageways (114, 116) forming a lubrication matrix for collecting a lubricant from an interior surface (312) of the guiding tube (310) to the rolling element bearing assembly (200).
